When Transporting - Panasonic LE1 Series Installation Instructions Manual

When Transporting

• It may need two or more people to carry
out the installation work.
• Be careful when picking up and moving
the indoor and outdoor units. Get a
partner to help, and bend your knees
when lifting to reduce strain on your
back. Sharp edges or thin aluminum
fins on the air conditioner can cut your
fingers.
When Installing...
Select an installation location which is
rigid and strong enough to support or
hold the unit, and select a location for
easy maintenance.
...In a Room
Properly insulate any tubing run inside
a room to prevent "sweating" that can
cause dripping and water damage to
walls and floors.
Keep the fire alarm and
the air outlet at least
CAUTION
1.5 m away from the unit.
...In Moist or Uneven Locations
Use a raised concrete pad or concrete
blocks to provide a solid, level foundation
for the outdoor unit. This prevents water
damage and abnormal vibration.
...In an Area with High Winds
Securely anchor the outdoor unit down
with bolts and a metal frame. Provide a
suitable air baffle.
...In a Snowy Area (for Heat Pump-
type Systems)
Install the outdoor unit on a raised
platform that is higher than drifting snow.
Provide snow vents.
When Connecting Refrigerant
Tubing
Pay particular attention to refrigerant
leakages.
WARNING
• When performing piping work,
do not mix air except for
specified refrigerant (R410A)
in refrigeration cycle. It causes
capacity down, and risk of
explosion and injury due to high
tension inside the refrigerant
cycle.
• If the refrigerant comes in contact
with a flame, it produces a toxic
gas.
• Do not add or replace refrigerant
other than specified type. It may
cause product damage, burst and
injury, etc.
• Ventilate the room immediately, in the
event that is refrigerant gas leaks during
the installation. Be careful not to allow
contact of the refrigerant gas with a
flame as this will cause the generation
of toxic gas.
• Keep all tubing runs as short as
possible.
• Apply refrigerant lubricant to the
matching surfaces of the flare and union
tubes before connecting them, then
tighten the nut with a torque wrench for
a leak-free connection.
• Check carefully for leaks before starting
the test run.
• Do not leak refrigerant while piping work
for an installation or re-installation, and
while repairing refrigeration parts.
Handle liquid refrigerant carefully as it
may cause frostbite.
